7 Running the motor
7.1 Quick start set-up
7.1.1 Basic connections
This section shows the basic connections which must be made for the
drive to run in the required mode. For minimal parameter settings to run
in each mode please see the relevant part of section 7.2
Quick Start
commissioning .
Table 7-1
Table 7-2
Speed feedback
Suitable devices are:
•
Incremental encoder (A, B),
• Resolver with 0.33 or 0.5 transformation ratio
• SINCOS encoder
Speed and position feedback
Suitable devices are:
•
Incremental encoder with commutation signals (A, B, U, V, W)
• Resolver with 0.33 or 0.5 transformation ratio
• Stegmann SINCOS encoder with Hiperface serial communications
For operation with a resolver or SINCOS encoder an option module is
required. For option module terminal information see section
10.16
Menu 16 Small option module set-up on page 171 or the manual
which is supplied with the option module.
7.1.2 Selecting the operating mode
Changing the operating mode returns all parameters to their default
value, including the motor parameters.
Procedure
1. Enter either of the following values in parameter 0.00 , as
appropriate:
1253 (Europe, 50Hz AC supply frequency)
1254 (USA, 60Hz AC supply frequency)
2. Change the setting of parameter 0.48 as follows:
The figures apply when serial communications are used.
3. Press or momentarily close the RESET contact.
The new setting takes effect and all the parameters revert to the
appropriate default values for the new mode.
Ensure that no damage or safety hazard could arise from the
motor starting unexpectedly.
Motor overload protection
The values of the motor parameters affect the protection of
the motor. The default values in the drive should not be relied
upon. It is essential that the correct value is entered in Pr
0.46
Motor rated current . The overload protection level is 150%
(SV: 175%) of motor rated current. The protection level
maybe adjusted below 150% if required. Refer to Chapter
8
Optimisation on page 92 for further information. These
settings affect the thermal protection of the motor.
If the keypad mode has been used previously, ensure that the
keypad reference has been set to 0 using the
and
buttons as if the drive is started using the keypad it will run to
the speed defined by the keypad reference (Pr
0.35 ).
If the intended maximum speed affects the safety of the
machinery, additional independent over-speed protection
must be used.
